MEXICO. Escudo, 1747-Mo MF. Mexico City Mint. Ferdinand VI. NGC EF-40. Fr-16; KM-114; Cal-Type 83 # 607; Cayon-10692; Grove-1095. A VERY RARE and seldom encountered one-year "Caveman" bust type. Imaginary bust design struck before the Madrid Mint delivered definitive standard portrait punches of the new monarch. Armored bust right, legend around; Reverse: Crowned arms of Spain flanked by Assayers initials and *I*; legend around. A wholesome survivor of this elusive type exhibiting a good strike with even wear consistent for the grade with plenty of remaining luster in the protected areas complemented by rich sunset hued patina adding to its pleasing appearance. A lovely example of this heavily sought after issue certain to be a welcome addition to the next collection it enters.
